comScore May 2012 US smartphone market share: same old.

No surprise.  While comScore shows 3-month change, the month-to-month change (April to May) showed that Google increased 0.1 percentage point; Apple jumped 1.5 percentage points; RIM declined 0.2 percentage points, and Microsoft was flat.

	Share (%) of Smartphone Subscribers
	Feb-12	May-12	Point Change
Total Smartphone Subscribers	100.0%	100.0%	N/A
Google	50.1%	50.9%	0.8
Apple	30.2%	31.9%	1.7
RIM	13.4%	11.4%	-2.0
Microsoft	3.9%	4.0%	0.1

This is what the long-term trends look like, with Google's growth slowing; Apple's growth has picked up again; RIM's decline slowed a bit; and Microsoft may have hit a bottom.  Having hit bottom though, it hasn't done anything much, having only increased 0.1 percentage point in four months -- it's just sitting there, doing nothing.
